Abstract
A method and an arrangement for operating a drive unit of a vehicle are suggested. Starting from a driver command torque which is converted into a resulting desired torque while considering additional torques, a correction of the resulting desired torque is undertaken in dependence upon the loss torques, which are not available for the drive. For realizing a negative torque command of the driver, the driver command torque is corrected with the loss torque weighted in dependence upon accelerator pedal position and rpm.
Claims10
A method for operating a drive motor of a vehicle, the method comprising the steps of:
- pregiving an input quantity for a torque of the drive motor in dependence upon a driver command;
- determining a deceleration command of the driver in dependence upon the accelerator pedal position and the engine rpm;
- and,
- superposing the deceleration command on the driver command to form a corrected driver command as the input quantity for the control of the drive motor.
An arrangement for operating a drive motor of a vehicle, comprising:
- an electronic control unit which inputs an input quantity for a torque of the drive motor in dependence upon the driver command;
- said control unit including means for determining a deceleration command of the driver in dependence upon accelerator pedal position and engine rpm;
- and,
- means for superposing the deceleration command of the driver on the driver command to form a corrected driver command as the input quantity for controlling the drive motor.
A computer program comprising a program code for carrying a method for operating a drive motor of a vehicle when the program is executed on a computer, the method including the steps of:
- pregiving an input quantity for a torque of the drive motor in dependence upon a driver command;
- determining a deceleration command of the driver in dependence upon the accelerator pedal position and the engine rpm;
- and,
- superposing the deceleration command on the driver command to form a corrected driver command as the input quantity for the control of the drive motor.
A computer program product comprising program code means stored on a computer readable data carrier in order to carry out the method for operating a drive motor of a vehicle, the method including the steps of:
- pregiving an input quantity for a torque of the drive motor in dependence upon a driver command;
- determining a deceleration command of the driver in dependence upon the accelerator pedal position and the engine rpm;
- and,
- superposing the deceleration command on the driver command to form a corrected driver command as the input quantity for the control of the drive motor.
